Synplus DL-1 5W/30 is a fully synthetic, low to mid SAPS, super high-performance engine oil which combines the latest development in oil formulation and additive technology to provide a lubricating oil with the highest level of protection whilst promoting fuel efficiency in modern low friction diesel engines.
Synplus DL-1 5W/30 is a stable, stay-in-grade catalyst and DPF compatible oil intended for use at extended drain intervals in car and light van diesel engines. These engines will be designed to be capable of using this low friction, low viscosity oil with a High Temperature / High Shear Rate (HTHS) viscosity of 2.9 mPa.s minimum.
Synplus DL-1 5W/30 meets the Japanese (JASO M355:2005 & M355:2017) DL-1 performance standard. This standard extends the existing DH-1 classification for diesel engines to recognise the different requirements of passenger car light diesel, and truck and bus diesel engines when using fuel with a maximum 0.005% sulphur content. Adding to the existing engine detergency, wear prevention and other performance benchmarks, there are the requirements to reduce the amount of soot (responsible for DPF clogging), and reduce the oil constituents that may impede catalyst performance.
Synplus DL-1 5W/30 meets today’s environmentally conscious market demands of reduced emissions and increased fuel efficiency. Benefits that will be accrued by the user of this oil include:

  • Longer drain intervals
  • Better fuel economy
  • Longer life for catalytic exhaust systems
  • Preserved performance of DPF and TWC filter systems

This oil is not suitable for all vehicles. Consult the owner’s manual or handbook if in doubt.
